Full-Stack Developer Salary in Seattle
Seattle offers a favorable salary-to-tax ratio. Base salaries run roughly 80–85% of SF levels, but Washington's zero state income tax means take-home pay is often within 5% of SF for the same role. Amazon alone employs over 50,000 engineers in the Puget Sound region, and AWS-specific roles (cloud, distributed systems, infra) carry a 10–15% premium over generalist engineering. Microsoft, Meta's Seattle office, and a growing cluster of Seattle-based startups round out the market. Cost of living is 40% above the national average — lower than SF or NYC but still high. A 1BR in Seattle proper averages $2,200/month.
